Phys.org / When biology inspires mathematics: Hidden symmetries explain why widely used evolutionary methods can give false answers
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this question using mathematical models that estimate how biological ...
Phys.org / Iguanodon shinbone growth may be first evidence of an infected skin ulcer in a dinosaur
Fossilized bones can reveal a wealth of details about animals, including their size, appearance, what they ate and any injuries they may have suffered. In a paper published in the journal Royal Society Open Science, researchers ...
Medical Xpress / Migraine treatment gets a rethink: New guide prioritizes patient voice and choice
A migraine headache can easily bring someone's usual day to a halt. The intense throbbing pain, usually on one side of the head, often comes with nausea, vision disturbances and light sensitivity. Preventive medicines work ...
Medical Xpress / Alcohol-linked cancer's toll extends far beyond the liver, with deaths rising across age groups
Alcohol-attributable cancer deaths in the U.S. doubled between 1990 and 2023, a new study found. The study also revealed that alcohol-linked cancer deaths are not limited to older adults or liver cancer. Among adults ages ...
Phys.org / Peacock-like displays outpace antlers and tusks in evolutionary change, model suggests
Many animal species, ranging from peacocks and birds of paradise to some lizards, fish and beetles, display physical features or ornaments that can attract potential mates. These ornaments can include colorful plumage, elaborate ...
Phys.org / Five-metal 2D catalysts could convert CO₂ to CO without needing an extra electrical boost
Carbon dioxide (CO₂) is usually discussed as something the world needs to get rid of. Activities such as the burning of fossil fuels for daily use, including electricity and transportation, and industrial applications release ...
Phys.org / Hubble tracks new decagon encircling Saturn's south pole
Recent observations with NASA's Hubble Space Telescope have revealed a giant, evolving, 10-sided atmospheric wave encircling Saturn's south pole. This discovery marks the first time a large, regular-sided jet pattern has ...
Tech Xplore / Why adding AI agents to a system sometimes reduces its performance
Computer scientists worldwide have been developing a wide range of artificial intelligence (AI) systems. Some of these systems rely on an individual AI agent, while others consist of multiple interacting agents that exchange ...
Dialog / Making superconductors thinner can change how they accommodate magnetic fields
What happens when a superconductor becomes so thin that electrons can no longer behave as if they were moving through an ordinary three-dimensional piece of metal? This question has been at the center of my recent work on ...
Medical Xpress / Low-dose THC keeps breast cancer cells in tumor models from reverting to an aggressive state
Recent discoveries have revealed that breast cancer cells are more flexible than previously thought. Some can change from a differentiated state, when a mature cell has taken on a specific function, back to a more stem-like ...
Phys.org / Trees use a 'muscle' to correct their posture—a newly discovered role for tension wood
A research team from INRAE and the University Clermont Auvergne has shown that trees are capable of correcting a curvature they detect in their stems through a specific biological process. In the study, young trees with bent ...
Phys.org / Trapped light generates nanoscale magnetization
Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance ...
